Google's faster-than-expected upgrade of all its SSL certificates to an RSA key length of 2048 bits will make cracking connections to the company's services more difficult without affecting performance, experts say.
Google said Monday the move from 1024-bit RSA, announced in May, was completed a month ahead of schedule and the company would start issuing the longer keys immediately.

The upgrade started a couple of weeks before former National Security Agency contractor Edward Snowden sent the nation in shock with revelations of NSA surveillance on Americans in its anti-terrorism program. Nevertheless, Google referred to government spying in announcing the upgrade's completion.
